the preparation of heteroditopic tpy-pincer bridging ligands, the synthon 4′-[C6H3(CH2Br)2-3,5]-2,2′:6′,2″-terpyridine} was synthesized. Facile introduction of diphenylphosphanyl groups in this synthon gave the ligand4′-[C6H3(CH2PPh2)2-3,5]-2,2′:6′,2″-terpyridine} ([tpyPC(H)P]). The asymmetric mononuclear complex [Fe(tpy)tpyPC(H)P}](PF6)2, prepared by selective coordination of [Fe(tpy)Cl3] to the

series of "push-pull" salts substituted with an electron-donating bis(N,N-dimethyl)aniline unit and different electron-withdrawing methyl or chelating pyridinium units have been designed and synthesized from Michler's ketone. The spectroscopic and electronic properties were investigated and compared to their DAST homologues. The studies revealed that a lower HOMO-LUMO gap is obtained in all cases, showing
